Yeah. Sometimes old hardware forces its hand and causes a big PITA.

I had a job working on VAX/VMS around 2009, but it was actually an emulator running on a PC because they just couldn't find any hardware to fix the VAX. At some point before I joined they had to get a ton of government approvals to use the emulator.

Fortunately they had a project to modernize the whole stack. And it was going to Solaris :-/
